Divide 33 photos into two groups so the ratio is 4 to 7, please help!!!!

Answers

Answer 1

Answer: The ratio 4 to 7 means that for every 4 photos in one group, there are 7 in the other group. So to divide the 33 photos into two groups with the ration 4 to 7 we can make a chart where we would have group one on one side and group two on the other. On one side we would increase by 4 each time and on the other side you would increase by 7 each time. Keep going until you find a row in where the numbers add to 33. So:

Group 1 / Group 2
4 7
8 14
12 21

Here we can see that 12 + 21 = 33 So in one group we will have 12 photos and the other group we will have 21 photos

Mrs. Johnson is buying every student in her math class a pencil and an eraser. Each pencil costs 25 cents and each eraser costs 15 cents. If x represents the number of students in Mrs. Johnson’s class, what is the equation for this

Answers

Answer:

Total amount spent by Mrs. Johnson : T(x) = 25x + 15x

Step-by-step explanation:

Cost of each pencil = 25 cents

Cost of each eraser = 15 cents

x is the number of students in the class.

So, total cost of erasers purchased= 15x

and total cost of pencils purchased = 25x

Hence, Mrs, Johnson Spends total amount on eraser and pencil = 25x + 15x

or, total amount spent by Mrs. Johnson: T(x) = 25x + 15x
